HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 540, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 431, 540, 715 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 431, 540, 715 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 431, 540, 715 is 1.
HCF(431, 540, 715) = 1
HCF of 431, 540, 715 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 431, 540, 715 is 1.
Highest Common Factor of 431,540,715 is 1
Step 1: Since 540 > 431, we apply the division lemma to 540 and 431, to get
540 = 431 x 1 + 109
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 109 and 431, to get
431 = 109 x 3 + 104
Step 3: We consider the new divisor 109 and the new remainder 104, and apply the division lemma to get
109 = 104 x 1 + 5
We consider the new divisor 104 and the new remainder 5,and apply the division lemma to get
104 = 5 x 20 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 431 and 540 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(104,5) = HCF(109,104) = HCF(431,109) = HCF(540,431) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 715 > 1, we apply the division lemma to 715 and 1, to get
715 = 1 x 715 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 715 is 1
Notice that 1 = HCF(715,1) .
